Working in the Satcom Team
At Open Cosmos we are solving the world’s biggest challenges from space, providing businesses, governments and researchers access to more readily available information than ever before - ready for the challenge?
The Satcom Team is responsible for modelling, simulating, and continuously optimising the performance of Open Cosmos’ satellite communication infrastructure. This includes the space segment, inter‑satellite links, terminals, and ground connectivity, ensuring our end‑to‑end systems deliver reliable, efficient, and scalable service under dynamic conditions.
We work with cutting‑edge technologies such as digital twins, autonomous networks, and large‑scale constellation models. The team plays a key role in design validation, mission planning, and performance‑driven engineering decision‑making.
What will you be doing?
As a User Terminal Architect, you will own the end‑to‑end architecture and technical definition of Open Cosmos’ satellite user terminal portfolio, spanning fixed, mobility, and highly integrated low‑power devices.
You will:
Define the complete architecture and technical specifications for all user terminal types, including fixed enterprise terminals, vehicular and aeronautical mobility solutions, and compact IoT and handheld devices.
Translate commercial, service, and system‑level requirements into clear, verifiable technical requirements across all terminal subsystems.
Lead the technical definition and integration of antenna systems, RF front ends, modems, digital processing, and power management architectures.
Drive critical trade‑offs across performance, size, weight, power, manufacturability, cost, and reliability, ensuring designs are suitable for mass production.
Ensure terminal designs meet required link performance, operational reliability, and regulatory constraints.
Define operational concepts for terminal activation, acquisition, tracking, handover, and remote management.
Specify requirements for autonomous operation, interference mitigation, diagnostics, and firmware or configuration updates.
Define test strategies and specifications covering type approval, over‑the‑air performance validation, EMC compliance, and quality assurance.
Provide technical models, data, and assumptions to support end‑to‑end system and network performance modelling.
Work closely with system, payload, RF, modem, manufacturing, and test teams to ensure successful delivery of scalable, mass‑producible terminals.
What You’ll bring
Deep understanding of end‑to‑end satellite user terminal architectures across fixed, mobility, and low‑power form factors.
Strong knowledge of antenna systems, including electronically steerable phased arrays and integrated low‑gain antennas.
In‑depth understanding of RF systems, including link budgets, noise figure, linearity, self‑interference, and cascade effects.
Confidence defining RF transceiver chains, modem integration, and power management architectures.
Strong grasp of digital modem and PHY‑layer processing.
The ability to translate commercial and system‑level needs into mass‑producible technical specifications.
Comfort making informed trade‑offs across performance, SWaP, manufacturability, cost, and reliability.
Understanding of user terminal operational concepts, including acquisition, tracking, handover, and remote management.
Familiarity with test strategies for OTA performance, regulatory compliance, and quality assurance.
Capability to develop and communicate system models and assumptions to support network‑level optimisation.
This role will be based in the UK or Spain.
